Here are 10 things to know about the next leader of the nation’s most populous state:

—Served as lieutenant governor from 2011 to 2019 and San Francisco mayor from 2004 to 2011.

—Married to Jennifer Siebel Newsom, a documentary filmmaker and actress, and the couple has four children. Newsom is the son of William Newsom III, a former justice on the state court of appeals.

—He is 51 years old.

—Opened a San Francisco wine shop in 1992 with Billy Getty, the grandson of the oil tycoon J. Paul Getty. It grew into a network of wineries, hotels and restaurants known as the PlumpJack Group. Newsom is placing his ownership into a blind trust run by a family friend and attorney to avoid conflicts of interest while serving as governor.

—Formerly married to Kimberly Guilfoyle, the prosecutor-turned-Fox news host who now dates Donald Trump Jr.

—Supported the 2016 ballot measure to legalize recreational marijuana, which won passage.

—Has dyslexia, a disorder that can make it difficult to read. Newsom said it’s forced him to learn how to over-prepare, and he memorizes most of his speeches.
